Review of Bearing Buddy Grease Caps BB2441

Today, we are going to be taking a look at the bearing buddy bearing protector, model 2441. These are going to replace the grease caps on the axle hub. The bearing buddy is going to prevent wheel bearing failure. What the bearing buddy does is it keeps water and dirt out of the hubs and bearings. It allows for boat trailer wheels to be completely submerged, and it's going to stop corrosion and pitting on the bearings. You're going to get two bearing buddies. Each was one is going to have a rubber cap that gets installed over the end of the bearing buddy.

Once you remove that, it's going to expose the grease fitting. That is going to be easily accessible. It makes adding grease to the bearings quick and simple. You don't ever have to worry about having to repack your bearings. This units a really great addition, keeps thing clean.

It's just very easy to use and maintain those components that are sometimes quite a mess to maintain. The unit's also designed to maintain slight controlled pressure, about 3 PSI with a spring loaded piston, which is going to prevent water from entering the hub. The unit also prevents over filling and rear shield damage, which is great. It's going to feature automatic pressure relief feature. If grease appears around the edge of the piston when filling with grease, this is a result of the automatic pressure relief feature functioning. The piston rides on a rubber O-ring, and once that piston strokes out beyond the O-ring, grease will escape in this area here.

That way the hub can't be over filled, and it can't be pressurized. The unit's constructed of stainless steel internal parts, and triple chrome plated steel barrel. It's going to ensure longer lasting fits, when compared to plastic or aluminum products. Again, it's going to include the rubbed covers to keep any grease of of you wheels. The bearing buddy's going to contain a grease fitting. It's going to have the spring.

It's going to have an O-ring It's going to have the piston, and eternally it's going to contain an outer bearing. The unit is assembled and ready for installation right out of the box. Installation is pretty simple. Just hold it against the hub, so this would go up against the hub. Hold it against the hub, and drive it into place with a small block of wood or a soft mallet. These are designed to fit 2.441 inch hub bores. Those are going to be commonly found on forty-four hundred, fifty-two hundred, six thousand pound, and seven thousand pound axles. Bearing buddies are made, right here, in the USA, and they are going to be covered with a lifetime warranty. That's going to do it for today's look at the bearing buddy bearing protectors, model 2441.



Will these bearing buddies work on my 1988 Prowler Lynx? Her weight is 3300 lbs. Thank you,

If your trailer hubs have a hub bore of 2.441" then this kit will fit. Attached is a link to our selection of Bearing Buddy covers in case you measure something else.
